Another Opteron 165 Thread 0547 tpmw

[The Sauce]

So my final max o/c was 285 x 9 = 2565 @ 1.425. Could not get stable higher than that at any reasonable voltage. That is exactly the same as my original 0536 stepping. I was hoping for at least a bit better with the newer stepping. I think I'm gonna take the IHS off and retry. If I get a better o/c with the IHS off I will sell my 0536. Temps do seem to be a bit better with this chip.

Guys..All cpus do not overclock this well..a couple report awesome results and we all think this is the norm

I have an opteron 170 0546 xpmw...."most" are hitting 2.7 ghz with ease

well stupid me did not go slow..I went ahead and 270x 10= 1.46 bios, 1.35*1.10%(my 165 did 2610 at this so I figure my 170 should do 2700)...locked up Prime 95 after 2.5hrs....

so I went ahead and tried 1.375*110%=1.52 and bios reposts 1.49...dual prime 95 for 4hrs..did not crash but locked winxp hard

BTW all temps were fine

Then I was not able to even boot 2700 with anything under 1.55v(1.375*113%) bios reports 1.54v...but it was dual prime95 stable for 8.5hrs when I stopped it last night(cpu load 50/52C, PWM is 64C..my 165@2610 temps are 46/48 load, PWM 58)

I should have gone slower...like I did with my 165....find stock vcore max and moving up

I feel pretty certain most 165-170 will hit 2500-2600 pretty high relaibilty..2700 is good bet on the 170...2800, the lucky few or real high volts

I am personally not thrilled with 1.55v on my DFI SLI DR

here is a interesting followup..I crashed Prime 95 a few nights back and could only boot 2700 with 1.55v..I tried 704-bta bios also...anyway I set everything to defaults and reflashed to 623-2 this was using the Tmod Bios cd

anyway, I retried 1.375*110=1.51v or bios reports 1.49v...I ran dual prime 95 lsmall fft last night for 10 hrs 17min before I stopped it this am

I have no idea why it stopped working and now is working...hope I do not have some weird boot issue

anyway, I wish I had moved slowly and started low working my way up..not done so to speak


this is with an OEM 0546xpmw.....I would really like a lower vcore still...not sure whether I should even try higher speeds..2700 is ok...wished for a dream chip of 2800 but I would prefer lower vcore

 

[freddy418]

good to hear. I have an 0546xpmw on the way as well, and I'd be incredibly happy if it did 2700 at 1.425 or less. I have heard that the "magic" threshold of 1.425 vcore is the difference between ~40C load temps and ~50C load temps so I'd probably stick with 2600 if it takes more than 1.425 to get to 2700.

so far my best effort (o547 tpmw) has been 270x9 (2430) that is dual prime stable at 1.37V. I cant get into windows at all beyond that even with increases in vcore. Would be nice to get to 2600 but I'm happy with the 600Mhz extra speed.

This is my first dual core and I'm impressed by the smoothness of my windows experience which was what I missed when I had my overclocked Pentium C and HT.

most of the 0546 xpmw that I have seen will require close to 1.5v for 2700..there are some around on verly vcore but those are sweet chips..I would expect to need 1.45v or more....

I am going to try and see if I can get lower vcore..but I had a weird issue and not sure why

As I had said I was doing dual prime 95 at2700 with I think it was 1.325*113% (this was after a dual prime 95 at 1.35*110% for 2hrs which hard locked xp too)and it hard locked winxp after 4hrs and then I could not get it to boot at anything lower than 1.5v at 2700

problem is I would get a post but it would not show verify DMI pool, back up cmos and boot cdrom...just hung and would restart....

What are the rest of your system specs? Seems that most folks are able to hit 2500 on this rev at stock volts.

I can go to 270x9 with a bump up in Vcore but beyond that I'm stopped cold. I've tried 1.5V but it will not go.

 

[nealh]

set the memory to 133 and 3-3-3-8 -1t for testing only and retry

also what bios are you using

My mistake, memory is set to 133.

BIOS is the lataest available from DFI: 6-23

Will try to loosen timings some more when i get home.

[pentiumobile]

I have a Opteron 165 CCBWE 0546 MPMW

2GB Corsair Value Ram

Epox 9NPA SLi

============================

I want to have a "mild"/"safe" OC, on stock voltages.

Lets say 2.4GHZ will be a superb improvement.

I dont have idea on where should I start.

Any guide will be apreciated.

[nealh]

First thing is it get installed and load up winxp and make sure things are ok at stock

next set mem divider to 133, keep loose timings 3-3-3-10-1t for example

I then set my bios to 1.35v and I set 2400 and my opteron 165 did this at 1.35v with no issues...tested dual prime 95 for 4 hrs and then went up to 2500 at 1.41v in bios and tested for 7 hrs ...I stopped to keep checking my overclock

I think if you set 1.4v you will get 2500 without much issue in most cases....and this is a small vcore bump with minimal incresed heat etc

once you know the cpu is ok ..go back and reset the ram and retest stability

 

[lopri]

Mine is so far.. amazing.. It's too early to tell since I know these opterons don't scale well with voltages. But even considering that, it's strange.. What I'm getting is;

Finally decided to open the box and popped-in the CPU. Then I tried 9x300 right way. I was like, what the hell, that's what my 144 did with the stock anyway, l'll give it a go.
It booted up! And the default voltage (auto) core reads 1.312V in CPU-Z! Then I tried Super PI 1M.. PASSED! OMFG! I started *gasping*

Well, at that point I realizee that it's a Dual-Core CPU. Hehe.. So I tried dual Super PI and failed instantly. But it was still impressive to be able to boot @2700MHz, with stock voltage of 1.312V
Currently doing my usual initial burning. Looking good, just praying that it'll scale well with voltages.. (I've seen many people reaching 2.6~2.7GHz with stock voltage and failed to reach 2.8GHz even with 1.6V)

My guess is that you will be 2.7GHz stable @~1.425V. I doubt if it will pay to go much higher.

 

[lopri]

Well, looks like I'm 2.7GHz stable @1.36V now. (Currently ~8hours)

 

[lopri]

I think I hit another jackpot. Initial burn success.

lopri - Nice chip there! Is it the stepping in the thread title? (0547 TPMW)

Ugh...now I'm really aggravated at my weak overclock.

dont be..most who get these processors are not posting..these results are not typical..look around ..its the same guys posting in several places and many are not getting 2800+

170 0546xpmw..I saw several post on getting to 2800..turns out most are hitting in things go well is 2700

these few individuals got an awesome chip..wish it was me...I was hoping to get 2750+ at low voltage..I am not just working to find the lowest prime95 stable vcore....mine chip is just ok

also most overclocks I see on the 165/170 are needing 1.5v for "good" overclocks..not 1.4v....

Yes!

 

[lopri]

Trying to get 2.8GHz out of it. I thought it'd be easy at relatively small voltage increase, but so far it doesn't seem to be the case. And temp rises DRAMATICALLY as volt goes up. It's very strange because my 4800+ doesn't behave like this.

Agreed. While I've been extremely lucky with my Opterons (148/144/165), today's Opterons are not what they used to be like 2~3 months ago.

One thing I'd like to recommend while OC'ing, especially for DFI users, is that having an active cooling over PWMIC area. Regardless of what DFI says (that PWMIC is designed to sustain up to 100C+), I believe my successful OC is partly dependant on it.

 

[KIAman]

Nice overclock lopri.

Your chip is doing better than mine did. My chip was not prime stable 2700Mhz at default (about 4 hours prime with 1 error on core0). I had to bump mine to 1.4 for 12+ hours prime.

Congrats!

It is wierd that the temps jump up so drastically once a little more vcore is applied. It doesn't follow any physical law. I thought temps should be more linear or at least smooth curve rather than such a sharp jump.

 

[OatMan]

Just got my Retail Boxed 0547 TPMW from Tankguys the other day. Currently I'm running an OEM 0541 RPMW @ 1.50v 292x9 = 2620 on my DFI Ultra-D. See the sig, both are 165s. My current CPU needs 1.65v to do 2700 which is not worth it to me, but I'm happy with it.

Basically I got a second chip to either keep as a spare running the better of the two, or if keeping the retial 3 year warrented chip and selling off the OEM 1 year warrented chip (only one month old)

anyway I'll post results of the new stepping to add to the "knowledge Base"
